A load draws between 100mA and 400mA at 6V. It is receivingpower from an unregulated DC power supply whose output voltage canvary between 8.5V and 12V. Design a Zener diode voltage regulatorusing a 6V Zener diode that regulates for diode currents greaterthan 4mA and has a maximum power rating of 6W. Show the circuitdiagram for the completed design and specify the power rating forall components.
